Phase II Study of the Hyper-CVAD Regimen in Sequential Combination With Blinatumomab With or Without Inotuzumab Ozogamicin as Frontline Therapy for Adults With B-Cell Lineage Acute Lymphocytic Leukemia
This phase II trial studies how well blinatumomab, inotuzumab ozogamicin, and combination chemotherapy work as frontline therapy in treating patients with B acute lymphoblastic leukemia. Immunotherapy with monoclonal antibodies, such as blinatumomab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Inotuzumab ozogamicin is a monoclonal antibody, called inotuzumab, linked to a toxic agent called ozogamicin. Inotuzumab attaches to CD22 positive cancer cells in a targeted way and delivers ozogamicin to kill them. Drugs used in chemotherapy, such as cyclophosphamide, vincristine sulfate, doxorubicin hydrochloride, dexamethasone, cytarabine, mercaptopurine, methotrexate, and prednisone work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving blinatumomab, inotuzumab ozogamicin, and combination chemotherapy may work better in treating patients with B acute lymphoblastic leukemia than chemotherapy alone.
• Patients with newly diagnosed, previously untreated B-lineage ALL or lymphoblastic lymphoma, or having achieved complete remission (CR) with one course of induction chemotherapy; patients who require steroids, cytarabine (ara-c) or hydrea to manage disease symptoms prior to finalization of diagnosis and treatment plan are allowed and eligible
• Failure to one induction course of chemotherapy (these patients will be analyzed separately); patients who require steroids, ara-c or hydrea to manage disease symptoms prior to finalization of diagnosis and treatment plan are allowed and eligible
• Performance status of 0-3
• Creatinine less than or equal to 2.0 mg/dL (unless considered tumor related)
• Bilirubin less than or equal to 2.0 mg/dL (unless considered tumor related)
• Adequate cardiac function as assessed by history and physical examination
• No active or co-existing malignancy with life expectancy less than 12 months, sources for the determination of clinical significance by the treating physician will be included in the subject's medical record
